Endophytic Detection in Selected European Herbal Plants.

A total of 181 cultivable endophytic bacterial isolates were collected from stems of 13 species of herbs inhabiting Europe (Poland): Chelidonium majus L., Elymus repens L., Erigeron annuus L., Euphrasia rostkoviana Hayne, Foeniculum vulgare L., Geranium pratense L., Humulus lupulus L., Matricaria chamomilla L., Mentha arvensis L., Papaver rhoeas L., Rosmarinus officinalis L., Solidago gigantea L. and Vinca minor L. The isolates were screened for their antifungal activity and fifty three were found to inhibit fungal growth. Of these, five had strong antifungal properties. These selected isolates were identified as: Pseudomonas azotoformans, P. cedrina, Bacillus subtilis group and Erwinia persicina.
